When to Wire EDM

Using a strand of wire as a cutting tool creates a linear line, and therefore Wire EDM services are commonly used to cut all of the way through the material. Wire EDM is best suited for projects that have intricate tolerances, material stress limitations, and/or surface finish requirements. Projects that do not require tight tolerances or finish, should consider waterjet cutting as a cheaper solution.

In the wire EDM cutting process, tolerance and surface finish are related, as both are controlled by the number of passes, or skims, the machine takes. The more skims, the higher the precision AND the better the finish.

Wire EDM can also be a high volume alternative for material types that are too brittle to be production stamped by a die. By stacking flat layers, machines are capable of wire EDM cutting high volumes of precision parts.

About Wire EDM

During wire electrical discharge machining (wire EDM), a single-strand of metal wire acts as the tool-electrode. This wire, which is commonly made of brass, creates an intense electrical field of spark that erodes material with great precision. Since the spark erosion process occurs at a fraction of an inch away from the material, no physical pressure is induced into the work piece.

KLH stocks 0.0018” wire that will yield a 0.0010” radius. Our thinnest wire is roughly one-half the size of a human hair.

Are you Nadcap certified/accredited?

Yes. KLH is accredited for Nonconventional Machining, including wire EDM and fast hole EDM. This achievement further solidifies KLH’s commitment to delivering the highest standards of aerospace machining.

How much wire EDM experience do you have?

Since 1987, when KLH was founded as a wire EDM job shop.

How many shifts do you operate on?

KLH operates on 24/7 availability. Our custom IT systems can even alert operators of job stoppages by email or text.
